Cartridge protractor- the best?

Hello. Would like some feedback on the best cartridge protractor for Rega P9 with RB1000 arm. Why do you recommend your choice? Thanks in advance!

More thumbs for Yip's arc protractor. Ie for the individual
combo TT-tonearm because the (different) dimensions of the spindle are accounted for.

Couldnt agree more with yip's mintlp. Highly accurate . Need bright light & suggest to set up with a 10 x 20 monocular

Can someone please explain how any of these alignment protractors being discussed that use line of sight from spindle to pivot can be as accurate as a protractor that uses an arm and pin/nail (Dr. Feikert or Clearaudio) that locks the protractor to the arm's pivot point ? Seems to me using line of sight, it would be easy to be off by a few millimeter's either way, resulting in an inaccurate cart alignment.

Rockitman, The arc protractor is a replica of the arc the
stylus is supposed to trace (aka 'eff. lenght') along the
record. On the Mint tractor you have also the 2 nul points.
The spindle - pivot distance determine where one need to
drill the hole for a given tonearm. Ie the arc protractor
'assume' that the spindle-pivot distance is already correct. All 'ordinary' protractors are made with this assumption.
